CHARLOTTETOWN, P.E.I. - Premier Wade MacLauchlan is calling on the federal government to require a more comprehensive impact assessment of Northern Pulp’s plans for a new effluent treatment facility for its Pictou County mill, citing concerns over P.E.I.’s lobster industry.

MacLauchlan has sent letters to both federal Environment Minister Catherine McKenna and Nova Scotia Premier Stephen McNeil expressing his concerns over the proposed facility’s plans to release wastewater from the pulp mill into the Northumberland Strait.

“I share the concerns of Nova Scotia and Prince Edward Island fishers that an outflow pipe placed into the Northumberland Strait could have unintended consequences for our commercial fishery and aquaculture industries,” MacLauchlan wrote.

“An effluent pipe that would allow as much as 75,000 cubic metres of fresh warm water to be directed daily into the Northumberland Strait is not a project that our government will support as proposed.”

Northern Pulp in Pictou, N.S., has been told by the N.S. government to replace the wastewater treatment facility at the mill by 2020. But, updating the facility could involve a process that would see wastewater drained into the Northumberland Strait, if it goes ahead as planned.

A more comprehensive impact assessment is required to determine the full scope of how the water and sea life could be affected by this development, MacLauchlan said.

“I understand that a Level 1 environmental assessment will be conducted this summer. I ask that a more comprehensive assessment take place and that the impact on Island fisheries is taken into consideration as part of this work,” he wrote to McKenna and McNeil.

“I am confident that we all agree that any development that risks the habitat and reproductive cycle of species such as lobster - or that threatens the livelihood of thousands of families dependent on the fisheries in the Northumberland Strait - cannot proceed.”

He added his wish to discuss this “environmentally sensitive matter in greater detail” with both ministers.

Kathy Cloutier, director of communications for Paper Excellence Canada which owns Northern Pulp, issued a written statement to media responding to MacLauchlan’s concerns.

She says the company is meeting the regulatory requirements set out by Nova Scotia’s Environment department and that it takes the responsibility of developing the new effluent treatment facility seriously.

“Effluent has been discharged into the Northumberland Strait for 50 years,” she said. “Effluent of today is not the same as decades ago as significant improvements have been made over the years.”

Cloutier said that the company expects to formally register the Effluent Treatment Facility Replacement project in late spring or early summer 2018.

“Prior to this as pre-registration consultation, Northern Pulp is committed to working with government, our neighboring communities, as well as the province of Prince Edward Island throughout this process to share information and address concerns,” she said.
